WINFIELD S. HUSON, OF TAUNTON, MASSACHUSETTS, ASSIGNOR TO THE CAMPBELLPRINTING PRESS AND MANUFACTURING COMPANY, OF NEW YORK, n. Y.

RATC H ET MOVEM ENT.

SPECIFICATION forming part of Letters Patent No.383,054, dated May 15,1888.

Application filed December 14, 1887. Serial No. 257,874.

To all whom it may concern:

Be it known that I, WINFIELD S. HUsoN, of Taunton, in the county ofBristol and State of Massachusetts, have invented anew and use fulRatchet Movement or Mechanism for Transmitting Power or Motion, whichinvention is 1 fully set forth and illustrated in the followingspecification and accompanying drawings.

The object of this invention is to provide a 1c ratchet motion ormechanism applicable to many uses, notably for the ink-fountains ofprinting-machines, and other purposes where intermittent action may bedesired, which mechanism shall be positive in action, and r5 avoid theuse of the usual pivoted pawl and its liability to fail to act throughthe breaking of springs, usually resorted to to cause them to engage theratchet. It is also the object to make a stronger construction than thathaving the pivoted pawl and to cheapen the whole.

In the accompanying drawings, Figure l is a side elevation of theratchet mechanism as the same may be applied to the inking apparatus ofaprintingmachine. Fig. 2 isa view 2 in plan of Fig. 1. Fig. 3 shows theratchet and pawl lever as in Figs. 1 and 2, except'that the pawl isdisengaged. Figs. 4 and 5 show two views of the ratchet-lever on anenlarged scale. Fig. 6 shows the pawl-lever as adapted to be operated byhand for ordinary drilling or other purposes.

In said figures the several parts are indicated by numbers as follows:

The number 1 indicates a part of the fram- 5 ing of a printing or othermachine; 2, a shaft journaled in said frame, making one revolution foreach required operation of the ratchet; 3, a slotted plate secured toshaft 2. A stud, 4, is adjustably secured in the slot of plate 3 by thetail-nut 5 for varying the number of ratcbetteeth which may be engagedby increasing or reducing the angular movement of the free end of thelever 10.

The number 6 indicates the end portion of a shaft such as anink-fountain roller of a printing-machine=-journaled in the frame 1. Ahand-wheel, 7, is secured thereto, by means of which the shaft orink-roller 6 may be ro-.

} tated by hand, when desired, independently (No model.)

of the ratchet-pawl. A smooth boss, 8, is formed on the frame 1,concentric with the shaft or ink-fountain roller 6. Secured to saidshaft 6 is a ratchet-wheel, 9. The length of said shaft 6 is immaterial.It may be long or short, even a mere hub, the purpose "it has toaccomplish in transmitting motion determining its length, and theratchet-wheel 9, instead of being secured to said shaft as a sep aratepiece, may be formed thereon as a part thereof. On the lever 10, uponone side, is formed or secured a fixed pawl, 11, and upon the other sidea fixed pin, 12. In the lever 10 is a slightly-elongated hole or eye,13, em-

bracing the shaft 6, the pin 12 being placed at about a right angle tothe line of elongation of the eye 13. The actuatingarm of the le ver 10is so placed that a line, X X, through the point of application of thepower 14, Fig. 7

4, and the pin 12 will be at about a right angle to the line Y Y, Fig.4, taken through the elongation of the eye 18. The pin 12 rests upon theconcentric hub 8, forming a suspendingfulcrum, upon which the lever 10may be oscillated by action of any power applied at 14, Fig. 4, toeffect the engagement and disengagement of the pawl 11, according as thepoint 14 is moved to the right or left. A con necting rod, 15, isarticulated at one end to the stud 4 and at the other end to a studflfi, secured in the hole 14 of the lever 10.

In Fig. 6 the application of the power to a ratchet and pawl is effectedby hand direct.

Having thus fully described my new ratchet mechanism as of my invention,I claim-- 1. A ratchet mechanism or movement consisting of thefollowing-named elements: a power-transmitting shaft provided withratchet-teeth, in combination with a boss concentrio with said shaft,and a power-lever provided with an elongated eye spanning said shaft, afulcrum-pin bearing on the circumference ofsaid boss, and arigid pawl,whereby, upon the application of a reciprocating force to the freed endof said lever, its pawl will positively engage and disengage saidratchetteeth and rotate accordingly the power-shaft, substantially asand for the purposes set forth.

2. An automatic ratchet mechanism or move nient consisting of thefollowing-named elements: a power-transmitting shaft provided withratchet-teeth, a boss concentric with said shaft, and a lever providedwith an elongated eye spanning said shaft, afnlcrum-pin bearing on thecircumference of said boss, and a rigid pawl, in combination withreciprocating mechanism connected to the free end of said lever,substantially as described, whereby the ratchet mechanism isautomaticallyoperated, substantially as and for the purposes set forth.

3. An automatic ratchet mechanism ormovement consisting of thefollowing-named elements: a power-transmitting shaft provided withratchet-teeth, a boss concentric with said shaft, and apawl-lever'provided with an elongated eye spanning said shaft, afulcrum-pin bearing on the circumference of said boss, and a rigid pawl,in combination with a rotary shaft, as 2, carrying a slotted plate, as3, an adjustable stud, as 4, and a connecting-rod articulated at one endto said stud and at the other to said pawl-lever, whereby theratchetshaft is intermittently and positively rotated and its degree ofrotation adjustably varied, substantially as and for the purposes setforth.
